What is the Frigidaire Dishwasher ER1 error?#
ER1 means the leak switch in your Frigidaire dishwasher has activated because it detected an active water leak in the base. This is an urgent, protect-your-home code — the machine is trying to stop a flood. My first instruction is always the same: shut off the dishwasher's water supply, then find where the water is escaping before you run another cycle. Do not clear ER1 and hope; the leak is real.
ER1 on a Frigidaire Dishwasher: likely causes and repair cost#
On a Frigidaire Dishwasher, the ER1 code signals: leak switch activated.
| Likely cause | Typical likelihood |
|---|---|
| Active water leak in base | Most common |
| Float switch stuck | Common |
| Condensation drip on float | Less common |
Typical professional repair: $100–$250 · Difficulty: moderate · usually a technician job
Symptoms that often accompany ER1: Dishwasher will not start; Error appears without visible water; Unit stops mid-cycle
Technician diagnostic sequence for ER1:
- Check the base pan for standing water — tilt unit forward slightly to access
- If base is dry, the float switch may be stuck in the up position — press it down
- Look for condensation drip patterns from the door seal or tub seam
- Run a cycle and watch for active leaks from underneath
Parts a technician may check or replace: float switch assembly; door gasket
Field note: ER1 can trigger from condensation alone — not always an active leak. Dry the base pan and press the float switch down. If ER1 does not return for several cycles, it was condensation.

How to troubleshoot the ER1 error yourself#
Handle ER1 as an active leak, not a nuisance code. Shut off the water supply valve under the sink, then cut power and pull the lower kick panel to look for standing water and its source. Common culprits are a loose or split hose clamp at the pump or inlet, a door gasket that has failed and lets wash water escape, and oversudsing from too much or the wrong detergent. If you find an obvious loose connection or a fouled gasket, fix it, dry the base pan completely, and the switch should reset. But if water keeps arriving and you cannot see where from, leave it off and call a technician — a hidden pump seal or tub seam leak is not worth the water damage of guessing, and this is exactly the case to stop DIY.
Is the Frigidaire Dishwasher ER1 error worth fixing?#
An ER1 repair runs $100 to $250 in most cases — a hose, clamp, or gasket at the low end, a pump seal at the higher end. That is small money against both a new dishwasher and the cost of repairing a water-damaged floor, so fixing it promptly is clearly worth it. The rare exception is a cracked tub, one of the few dishwasher failures where replacement can beat repair. Otherwise, stop the leak, make the repair, and get the machine back in service safely.

Frigidaire Dishwasher ER1: frequently asked questions#
What does the ER1 error mean on a Frigidaire dishwasher?#
ER1 means the leak switch has activated on an active water leak in the base of the machine. The dishwasher stops to prevent water from reaching your floor.
Is it safe to keep using a Frigidaire dishwasher showing ER1?#
No. ER1 signals a live leak, so running the machine risks flooding. Shut off the water and find the source before using it again.
Can I clear the ER1 error myself?#
If the leak is a loose hose, a fouled gasket, or oversudsing, you can fix it and dry the base to reset. A hidden pump or tub leak needs a technician.
How much does it cost to repair ER1 on a Frigidaire dishwasher?#
A professional repair typically runs $100 to $250, depending on whether it is a hose and gasket fix or a pump seal.
Which parts usually fail when a dishwasher throws ER1?#
Hose connections, the door gasket, and the pump seal are the common leak sources behind ER1.
Why does an active water leak in the base trigger the ER1 error?#
A float or leak switch sits in the base pan. When escaping water raises it, the switch activates and the control reports ER1 to stop the leak from spreading.
Is a Frigidaire dishwasher with ER1 worth repairing?#
Yes, and promptly — a $100 to $250 repair is far cheaper than water damage or a new machine, unless the tub is cracked.
